This has been factored in, in that we have the notion of a snapshot at
the top-level statement which needs to guarantee certain consistency
constraints.

Note that we expect the update language to be used in many different
transaction environments and thus do not define a single transactional
semantics. This means you could use the statements in a fully
serializable transaction, or in an optimistic CC environment.
